With official confirmation pending as we went to press, Fiorina called the result an important milestone in bringing the two companies together, despite the closeness of the vote, which is expected to be just one or two percentage points in favour of the merger.
With estimates of 15,000 job losses expected to follow the merger going through, users are demanding a rapid plan of action from the new company.
The merger will affect thousands of UK companies that depend on technology from the two suppliers.
Ian Severn, chairman of the user group CompaqUsers.Org, said, "The users would like to see a very quick conclusion to the merger situation. We need to understand the roadmaps that are going to be in place as soon as possible and to that end we are trying to co-ordinate meetings for the users."
In anticipation of a "yes" vote from the shareholders, HP has been working out the details of the post-acceptance roadmaps. "Our team of more than 900 HP and Compaq employees continues the integration planning that will enable us to be up and running from day one," said Fiorina.
